That's the failure, and this...

... seems to be the cause, the MMIO aperture is either not configured
or not implemented by hardware - I've seen both on Sun hardware. This
appears to be a Rage II, so it's not implemented. The driver *should*
fall back to using the I/O aperture, which may or may not work
correctly either, at 0x0. Failing that, it should use the register
mapping in the main aperture. Something in that logic is apparently
broken.
Please post the card's pcictl dump output and ( assuming you're using
machfb ) the machfb output from dmesg.

No, not in 7.0 and not yet in -current.
The failure seems to happen before either XAA or EXA could take over.

The Rage II in my beige G3 ( which has no MMIO aperture ) works fine,
although that's -current. I have a 2MB Rage II with Sun firmware
somewhere, let me dig it up and see if I can reproduce the failure.

have fun
